Study Notes
Joint Between the Axis and Occipital Bone
- The joint between the axis (C2) and the occipital bone is called the atlanto-occipital joint.
Distinguishing Vertebrae in the Vertebral Column
- Vertebrae can be distinguished by their size, shape, and features:
- Cervical vertebrae: smaller, with transverse foramen
- Thoracic vertebrae: medium-sized, with rib facets
- Lumbar vertebrae: larger, robust bodies to support weight
Role of Principal Ligaments of the Vertebral Column
- Principal ligaments provide structural support, stability, and limit excessive movement, contributing to injury prevention.
- Key ligaments include:
- Anterior longitudinal ligament: prevents hyperextension
- Posterior longitudinal ligament: prevents hyperflexion
Attachment Points on a Typical Vertebra
- The transverse process and spinous process of a typical vertebra serve as primary attachment points for muscles and ligaments.
Joint Between Adjacent Vertebrae
- The joint between adjacent vertebrae, allowing for flexion and extension, is called the intervertebral joint.
Number of Cervical Vertebrae
- There are seven cervical vertebrae in the cervical region of the vertebral column.
Ligament Connecting Spinous Processes
- The ligament that connects the spinous processes of the vertebrae is known as the supraspinous ligament, aiding in vertebral column alignment.
Joint Between Atlas and Axis
- The joint between the atlas (C1) and the axis (C2) is called the atlantoaxial joint, allowing for rotational movement of the head.
